Microcontrollers Procurement Notes

Verify the specific suffix 'V' against official Microchip documentation to confirm it denotes the standard commercial/industrial temperature grade and voltage range as defined in the datasheet. Ensure the package type matches the required PCB footprint, as this model is available in QFN and TQFP configurations. Cross-reference the full part number with the manufacturer's current product status to confirm availability and lifecycle stage before finalizing procurement plans.

Microcontrollers Selection Notes

Select this component when a design requires a balance of processing performance and rich peripheral integration within a compact form factor. It is suitable for applications needing USB OTG and CAN capabilities alongside analog features like CTMU and comparators. Consider the 50 MHz maximum clock speed and 128 KB memory capacity against application software complexity. Verify that the 64-pin package constraints align with the necessary I/O count and thermal requirements for the target environment.

Microcontrollers Part Context

This device belongs to the PIC32MX1XX/2XX/5XX 64/100-Pin Family, designed for cost-sensitive and space-constrained embedded applications. The series provides MIPS32 M4K core performance with specialized peripherals for audio, graphics, and touch interfaces. It serves as a scalable solution within the Microchip portfolio, offering migration paths from lower-end PIC32MX models while maintaining compatibility with the MPLAB X development ecosystem.

Microcontrollers Replacement Considerations

Consult the official datasheet Table 1 for pin-compatible alternatives within the same family, such as the PIC32MX530F128L variant which utilizes a 100-pin package. Substitution with other PIC32MX series members requires verification of memory size, peripheral availability, and package dimensions to ensure mechanical and functional equivalence.
